Every time zenitsu kisses them he zaps them. Every time they touch it's like a little static shock. The more prolonged physical contact, the more he gets used to it. When they kiss for the first time, the shock was tingling, from their lips, to the tips of their hair, even to their toes. Their hair was standing on end. Zenitsu looks at them nervously, his face tinted pink. They pull away with wide eyes, and an even wider smile. "Again." He looks at them like they shocked him! The longer they try to kiss, the more intense the shock when they go back in. So they have to take breaks. This phenomenon also happened when they first started holding hands, etc. Eventually after continuous exposure, he got used to it so it's more of a pleasant tingling sensation. "I'll just shock you more!" He whines. He wants more but tries to resist, attempting to push them off. "We'll just have to raise your tolerance then." They replied smirking, seeing him go red in the face, going in for another. He whimpers as their lips meet and melts into the kiss. "I know you don't want to hurt me, but I'm pretty used to it at this point. I'm convinced I have a higher shock tolerance than most people. It's what I like to call Zenitsu conversion therapy. Your affection just comes with little zaps, and I'm perfectly okay with that."
